AUTOMATIC FILING LUBRICAER Application led March 22, 1930. Serial No. 438,211-,

y This invention relates to lubricators, and has for one of its objects to providel a novel", simple and highly efiicient device of thischar'- acter which shall be adapted to be used for the purposeof lubricating Vpil-ing, fender boards and guard rails and which shally beY adapted to be applied to a ferryA boat, tug boat, car float or any other water crat in a `manner to effect the automatic lubrication lo of the parts stated when the craft isV coming into port and immediatelypp'rior to con;- tact with the piling. e

With the foregoing and other objects inV View, the nature of which will appear as the description proceeds, the invention consists in the. construction, combination and ar rangement of parts hereinafter fully de'- scribed and claimed, and illustrated in the accompanying drawings, wherein Figure 1 is a view in side elevation of the lubricator applied to a water craft:

Figure 2 is a sectional' view on an enlarged scale taken on the horizontal plane'indicatedv by the line 2-2 of Figure 1, andV Figure 3 is a sectional View on an enlarged scale taken on the vertical plane indicated by the line 3-3 of Figure 2.

Referring in detail" to the drawings," 1 designates the gua-rd rail, 2 the outside wall, and 3 the upper deck of a ferry boat, these gli,

parts being shown in order to illustratev the manner in which the lubricator is adapted to be applied to a boat of this type. Whi-le the lubricator is shown as applied toa ferryboat, it is to be understood that it is adapted to be applied to a water craft of any other type;

The lubricator comprises a pump twhfich embodies a cylinder 5 and a solid recipro-` cating piston 6; The cylinder 5 is carriedby a base plate 7 which is mounted uponA the guard rail 1 and is secured thereto by bolts 8. TheV cylinder 5 extends transversely of l the guard rail 1, andk its outer end isspaced inwardly from the outeredge of the guard rail. The cylinder 5 is preferably formed integrally with a base plate 7, and also y formed integrally therewith' and with thei `5`0* cylinder are apertured lugs 9 which extend' upwardly" from the base from thev cylinder.

- Thel pis-ton 6` extends through the outerplaste and radially y end of the cylinder 5 and is provided: at its:`

outer end with' a screw threaded stud 10'. 555 bumper barjli is provided at al point centrally between its ends with a screw threaded socketv 12 which opens through the inner sid'eof the bumper bar and' is engaged withV the stud lO. li'olts 13 which slida-bly pass-e di through the openingsv 14:' of thel lugs 9, have their outer ends screw threadedly' engaged',

as as1`5`-, with thebiunper bar 1&1, and have' their heads 16 arrang'edV atl the inner sidesoi theillugsi The boltsf 1535, whichl are located at oppositesides of the piston 6', cooperate with the piston' toy support the bumper bar 11I in a pararllbl or substantia'lly' parallel; posi#- tionl with respect to: and above the guardv l Y rail 1, and these'pa-rts also hold the bumper 'To'x bar against any turning movement about the longitudinali andE transverse aires: of the cyl# Y inder 5';

The' bumpery bar 11 constitutes an; actuatingl member for the piston 6, vand itsi outer 'Iiix side normally extends outwardlyl beyond? the outeredge o f the uardl rail 1. The bumper bar'11 is held in-t "ispositionwith respect to to theouter'edge of the guard rail' 1 by coil springs'l? which are mounted' upon thebo'lts' gi 13' betweenL the' guard rail andl the lugs 9". The heads 1&6 oi" the bolts 113L cooperate with thev lugs 9`to limit't'he outward movement of: the bumper bar 11 under the"A influence ofthe' spring 1?.l When" the bumper bar 1-11 is in etiJ this position, the piston 6v is at the limit" of" its outward stroke. The terminald portions of: the outer sidejoftheibumper bar 151i are rounded, asat 11'.

lA distributing 'pipe 18 is mounted uponi-` 90"' thfeguardra'lf 1 closeto; andln parallel relation' with the' outer; edge of the` rail-v and'4 ist providedV at; intervals in theA lengthl thereof be secured by clips` 20 or in any other suit- 95" able' manner to: the guard rail 1t, and it isvv closeds at Aits endjs: The nozzles 1'9i extend downwardly and outwardly from the pipe? lfgand are provided'f'at theirouter ends with* discharge p'orts21. The no`zz`l'es191` are pro- 10'0 vided with spring controlled check valves 22 which seat inwardly to'prevent air from be-4 ing drawn into the pipe 18 by Way of the nozzles. A pipe 23 extends from the rear end of the cylinder 5 to a point intermediate the length of the distributing pipe 18 to per mit lubricant to be forced from the cylinder into the distributing pipe by the inward strokes of the piston 6. The pipe 23 is provided with a spring controlled check valve 24 which seats in the direction of the cylinder 5 to prevent lubricant from being drawn from the pipe into the cylinder during the out ward strokes of the piston 6.

The lubricant is carried in a reservoir 25 which may be supported from the upper deck 3 by brackets 26 or in any other suitable manner. The lubricant is conveyed from the reservoir 25 to a chamber 27 by a pipe 28 which is provided with a cut-olf valve 29. The chamber 27 is secured, as at 30, to the rear end of the cylinder 5, and is provided in its front side with an opening by which communication between the chamber and cylinder is established. The wall of this opening is beveled to provide a seat 31 for the valve 32 which opens in the direction of the cylinder to permit the lubricant to be drawn into the latter during the outward strokes of the piston 6. The valve 32 is carried by a rod 33 which is slidably mounted in a guide 35 carried by the outer side of the chamber 27. A coil spring 36 which surrounds the rod 33 between the inner side of the chamber 27 and a stop 37 carried by the inner end of the stein, serves to yieldingly hold the valve 32 against its seat 31. A housing 38 for the outer end of the valve stem 33 and spring 36 is secured, as at '39, to the inner side of the chamber 27.

As it extends outwardly beyond the guard rail 1 of the craft, the bumper bar 11 will contact with piling when the craft is coming into port and immediately before the guard rail contacts with the piling, with the result that it will be moved inwardly against the tension of the spring 17. This movement of the bumper bar 11 will impart an inward stroke to the piston 6, with the result that the lubricant in the cylinder 5 will be forced therefrom into the pipe 18 by Way of the pipe 3, the lubricant spraying out of the nozzles 19 onto the guard rail and piling in sufficient quantity to effect the lubrication of such When the force acting against the bumper bar 11 to force it and the piston 6 inwardly ceases to act, the springs 17 will reactY and force these parts outwardly, with the result that a fresh supply of lubricant isdrawn into the cylinder 5; During the outward strokes of the piston 6, the valves 22 and'24 seat to.

prevent air from Ybeing drawn into the cyl inder 5, and the valve 32 unseatsto permit the lubricant to be drawn into the cylinder.

During the inward strokes of the piston 6, the valve 32 seats to prevent the lubricant from being forced from the cylinder 5 into the chamber 27, and the valves 24 and 22 unseat to permit the lubricant to be forced from the cylinder and out through the nozzles 19 by way of the pipes 23 and 18. To permit it to be primed or initially charged with a supply of lubricant, the cylinder 5 is provided with an air vent 40.
